To all whom, it may concern:

Be it known that I, WALTER J. CooMBs, of l Quincy, in the county of Norfolk and State of Massachusetts, have inventedcertain new I and useful Improvements in Lacing Hook or Stud Setting Machines, of which the following is a specification.

The invention relates to machines for seti ting lacing hooks or studs in shoe-uppers, and more especially to means for insuring the removal of a set stud from the setting devices immediately afterthe setting operation, so that it shall not interfere with the i presenting of the next succeeding hook or stud to the setting devices when running the machine at a high rate of speed.

In setting hooks or studs upon shoe-uppers it is the usual practice for the operator to hold the upper in position to receive the hook or stud and to move the upper forward after each setting operation in order to properly space the studs or hooks along the edge of the upper. When running a machine at high speed, the operator sometimes fails to advance the work quickly enough after the setting operation to free the set hook or stud from the setting devices before these devices have returned into position to receive the succeeding stud, thus causing delay in the performance of the Work and frequently injuring or spoiling the work.

In practicing my invention I insure the removal or freeing of the stud from the setting devices after each setting operation by provi ding an ejector which engages the set stud and discharges or frees it from the setting device after the setting operation and before the return of the setting devices to position to receive the succeeding stud or before the stud is fed to the setting devices, thus avoid# ing all danger of an interruption in the proper operation of the feeding and setting devices.

The form, construction, and arrangement of the ejector may be varied to correspond with the specific construction and arrangefor feeding the hooks or studs thereto without departing from my invention, which consists in the features and combinations hereinafter set forth in the claims. l

For the purpose of illustration I have i shown Amy invention embodied inta hook or stud setting machine in which. the hooks are fed to a reciprocating hook-supporting plate, which carries them against a stationary setting-anvil, the setting devices and feeding devices having Vthe same general arrangement as these devices in the machine shown in the patent to W. C. Bray, Nio.277 ,985, May 22, 1883.

So much of this machine as isnecessary to illustrate the features of the invention is shown in the accompanyingv drawings, in which` Figure l is a partial side elevation, of the machine. Fig. 2 is a sectional detail of` the devices for feeding the hooks` to, the setting devices. Fig. 3 is a plan view of the hooksupporting plate. Fig. 4 is a detait view of a part of the setting devices, and Figs. 5, 6, and 7 are views showing the setting devices and ejector in the different positions which, they assume in the operations of setting the hook and4 freeing it from the setting devices.

In the machine shown in the drawingsl` the setting devices consist of a stationaryanvil A and a hook-supporting plate B, mounted on a vertically-reciproeating plungerJ The plunger is reciprocated at proper-.intervals by means of a cam B2, engaging one end of a lever B3, the other end of which engages the plunger B, the lever being held inl engagement with the cam by means of a springB, surrounding the plunger.

Vhen ,the plunger B is in itsl lowerv position, as indicated in Fig. 2, a recess B5 in the plate B is in position at themouth of a guidewayC, through which the hooks are, fed to the supporting-plate. When the plunger and supporting-plate arein. thisposition, the side B6` of the recess B5 forms a continuation of one side of the guideway C, while an overhanging lip B7 on a block B8 forms the continuation of the other side of the guideway. The hook is therefore accurately guided into position on the plate Bas it is. fed forward by the reciprocating feeding-finger D the manner fully explained in the patent referred to. As the hook passes on to the plateB the head of the hook passes over a spring-pressed hook in popin B9,'which serves to retainthe v Y sition on the plate as the hook is carried IOO on the lever.

the upper 'position against the anvil A. The block BB is held in fixed position at the mouth of the guideway C by means of a pin B10, and the plunger B is provided with a slot B11, in which the block B8 plays as the plunger is reciprocated. When the plunger B is raised, therefore, the plate B is moved away from the upper end of the block B8, so that the hook may be freed from the plate by moving it laterally away from the side B of the recess B5.

After the hook has been set as indicated in Fig. 6 the work is spaced or fed forward by the operator as the plunger descends, and this movement must take place before the plunger has descended far enough to bring the head of the hook into the plane of the upper end cf the block B8, as otherwise the lateral movement of the hook will be prevented or arrested by the block B8. In order to insure this lateral movement of the hook before the plunger has descended sufficiently to interfere with its lateral movement, I provide an ejector in the form of a pin E, mounted in the. plunger B and arranged to move under the plate B in a direction to force the head of the hook laterally off the plate. This ejector-pin E is held in retracted position by means of a spring E7, which forces the outer end of the pin against the upper end of a lever E7. The outward movement of the lever is limited by a slioulder E3, which is engaged by a projection E4 The lever is mounted in alug E5, secured to the plunger B', and is provided with a projecting arm E, through which it is operated to advance the ejector-piii E at the proper time. The lever is operated by means of an abutment E7, arranged in the path of the arm EG. This abutment E7 is formed on end of an arm E8, pivoted to a 'fixed part of the machine and held in normal by means of a spring E".

When the parts are in the position shown in Fig. 5, the plate B is in position to receive a hook, the ejector-pin being in its retracted position, so that it does not interfere with the feed of the hooks to the supportingplate. As the plunger rises the arm EU' of the lever E7 rides against a cain-surface E1o on the arm E8, pressing said arm backward against the tension of its spring until the arm E passes above the abutment E7, when the arm Esas returned to normal position by itsspring, as indicated in Fig. 6. After the hook has been set in the material, as indicated in Fig. 6, the plunger B descends, and as it descends the arm E(5 rides against the abutment E7, rocking the lever E7, and thus advancing the ejector-,pin E so that it forces the hook laterally ofl' the plate B, as indicated in Fig. 7. As soon as the arm E? passes by the abutment E7 the ejector-pin is immediately returned to normal position by its spring ready for the feed of the neXt hook to the hook-supporting plate.

ssa/W9 While I have shown the invention embodied in a machine in which the hooks are fed to a reciprocating supporting-plate and in which the setting-anvil is arranged above the reciprocating plate, it will be understood that the invention may be applied to machines in which the positions of the anvil and plate are reversed or in machines in which either part of the setting devices is a moving part or in machines in which the setting and feeding devices are otherwise constructed and arranged.
